AccountKiller

Want to delete your account on a site but can't figure out how? AccountKiller can help. It's got deletion instructions for most of the biggest sites, and they're ranked by ease. Some companies, like AOL, make it as hard as possible to close your account, but this site is a great resource for thwarting them. The only reason I'm not giving this 5 stars is because the layout/copy isn't amazing, but otherwise it's awesome.

This website will make your life easier when you want to delete an account. They don't have instructions for all websites, but they have a large range of sites listed. They have set out three colour coded groups: white, grey and black. The white ones are easy to delete, the grey are moderate and can take some time while the black groups are permanent accounts you cannot delete.
